Abstract

This paper investigates the use of statistical control techniques such as (statistical control
charts and process capability) in quality control of the electrical wires and cables which were
produced in Ur Company (Cable factories) and in order to evaluate the performance of the
manufacturing machines. Two types of manufacturing processes were selected namely (drawing and insulation) by testing diameter, max. tensile strength, elongation, and electrical
resistance of wires, and testing of nominal thickness, strength, and elongation of insulation
and sheathing of cables, for evaluating of quality control and process capability by using
control charts namely (Average-Range) chart and process capability calculations and
statistical analysis based on histogram technique. The results showed that some of machines
are unable to satisfy the specification tolerances due to wide differences in the resulted values
of the statistical parameter. Therefore, it is important to carry out the total maintenance for
these machines, and increase the quality control activities such as testing the raw materials by
chemical analysis
